EWAN McGregor says he is on the look out for the "next great story to direct".

The Scottish actor is hoping to forge a career behind the camera after making his directorial debut with American Pastoral, an adaptation of Philip Roth's Pulitzer Prize-winning novel, in which he also stars.

McGregor, 45, joined co-stars Jennifer Connelly and Dakota Fanning at the film's Los Angeles premiere where he revealed he was already thinking ahead to the future and looking for his next movie to direct.

He told the Press Association: "Having done it for the first time, the responsibility of a feature film on your shoulders and one that's based on this enormously popular Pulitzer Prize-winning novel is quite great.
